     1→# Claude Logbook
     2→
     3→A Python CLI tool that converts Claude transcript JSONL files into readable HTML format.
     4→
     5→## Project Overview
     6→
     7→This tool processes Claude Code transcript files (stored as JSONL) and generates clean, minimalist HTML pages showing user prompts chronologically. It's designed to create a readable log of your Claude interactions.
     8→
     9→## Key Features
    10→
    11→- **Single File or Directory Processing**: Convert individual JSONL files or entire directories
    12→- **Chronological Ordering**: All messages sorted by timestamp across sessions
    13→- **Session Demarcation**: Clear visual separators between different transcript sessions
    14→- **User-Focused**: Shows only user messages by default (assistant responses filtered out)
    15→- **Space-Efficient Layout**: Compact design optimized for content density
    16→- **CLI Interface**: Simple command-line tool using Click
    17→

     5→## Project Overview
     6→
     7→This tool processes Claude Code transcript files (stored as JSONL) and generates clean, minimalist HTML pages showing user prompts chronologically. It's designed to create a readable log of your Claude interactions.
     8→
     9→## Key Features
    10→
    11→- **Single File or Directory Processing**: Convert individual JSONL files or entire directories
    12→- **Chronological Ordering**: All messages sorted by timestamp across sessions
    13→- **Session Demarcation**: Clear visual separators between different transcript sessions
    14→- **User-Focused**: Shows only user messages by default (assistant responses filtered out)
    15→- **Date Range Filtering**: Filter messages by date range using natural language (e.g., "today", "yesterday", "last week")
    16→- **Summary Support**: Display summary messages with highlighted formatting
    17→- **System Command Visibility**: Show system commands (like `init`) in expandable details rather than hiding them
    18→- **Markdown Rendering**: Automatic markdown rendering in message content using marked.js
    19→- **Space-Efficient Layout**: Compact design optimized for content density
    20→- **CLI Interface**: Simple command-line tool using Click
    21→

     1→# Claude Code Log
     2→
     3→A Python CLI tool that converts Claude transcript JSONL files into readable HTML format.
     4→
     5→## Project Overview
     6→
     7→This tool processes Claude Code transcript files (stored as JSONL) and generates clean, minimalist HTML pages showing user prompts chronologically. It's designed to create a readable log of your Claude interactions.
     8→
     9→## Key Features
    10→
    11→- **Single File or Directory Processing**: Convert individual JSONL files or entire directories
    12→- **Chronological Ordering**: All messages sorted by timestamp across sessions
    13→- **Session Demarcation**: Clear visual separators between different transcript sessions
    14→- **User-Focused**: Shows only user messages by default (assistant responses filtered out)
    15→- **Date Range Filtering**: Filter messages by date range using natural language (e.g., "today", "yesterday", "last week")
    16→- **Summary Support**: Display summary messages with highlighted formatting
    17→- **System Command Visibility**: Show system commands (like `init`) in expandable details
    18→- **Markdown Rendering**: Automatic markdown rendering in message content using marked.js
    19→- **Space-Efficient Layout**: Compact design optimized for content density
    20→- **CLI Interface**: Simple command-line tool using Click
    21→
    22→## Usage
    23→
    24→```bash
    25→# Single file
    26→claude-code-log transcript.jsonl
    27→
    28→# Entire directory
    29→claude-code-log /path/to/transcript/directory
    30→
    31→# Custom output location
    32→claude-code-log /path/to/directory -o combined_transcripts.html
    33→
    34→# Open in browser after conversion
    35→claude-code-log /path/to/directory --open-browser
    36→
    37→# Filter by date range (supports natural language)
    38→claude-code-log /path/to/directory --from-date "yesterday" --to-date "today"
    39→claude-code-log /path/to/directory --from-date "last week"
    40→claude-code-log /path/to/directory --from-date "3 days ago" --to-date "yesterday"
    41→```

   141→            
   142→What to add:
   143→1. Commands that will be commonly used, such as how to build, lint, and run tests. Include the necessary commands to develop in this codebase, such as how to run a single test.
   144→2. High-level code architecture and structure so that future instances can be productive more quickly. Focus on the &quot;big picture&quot; architecture that requires reading multiple files to understand
   145→
   146→Usage notes:
   147→- If there&#x27;s already a CLAUDE.md, suggest improvements to it.
   148→- When you make the initial CLAUDE.md, do not repeat yourself and do not include obvious instructions like &quot;Provide helpful error messages to users&quot;, &quot;Write unit tests for all new utilities&quot;, &quot;Never include sensitive information (API keys, tokens) in code or commits&quot; 
   149→- Avoid listing every component or file structure that can be easily discovered

Based on my comprehensive analysis of the `.examples/full.jsonl` file, I can provide you with a detailed breakdown of all the different JSON object types and their properties. Here's my analysis:

## JSON Object Types and Structures

### 1. **Base Message Object** (Common to all messages)
All messages share these common properties:

```typescript
{
  parentUuid: string | null,
  isSidechain: boolean,
  userType: string, // "external" 
  cwd: string,
  sessionId: string,
  version: string, // e.g., "1.0.24"
  type: string, // "user" | "assistant"
  uuid: string,
  timestamp: string, // ISO 8601 format
  message: MessageContent
}
```

### 2. **User Message Type** (`type: "user"`)
```typescript
{
  // ...base properties
  type: "user",
  message: {
    role: "user",
    content: string | ContentItem[]
  },
  toolUseResult?: ToolUseResult // Present when this is a tool result message
}
```

### 3. **Assistant Message Type** (`type: "assistant"`)
```typescript
{
  // ...base properties  
  type: "assistant",
  message: {
    id: string, // e.g., "msg_01M62oUQ8GWvFQ4xueDLdeXf"
    type: "message",
    role: "assistant",
    model: string, // e.g., "claude-sonnet-4-20250514"
    content: ContentItem[],
    stop_reason: null,
    stop_sequence: null,
    usage: {
      input_tokens: number,
      cache_creation_input_tokens: number,
      cache_read_input_tokens: number,
      output_tokens: number,
      service_tier: string // "standard"
    }
  },
  requestId: string // e.g., "req_011CQ841ux7YzvbPnxV7YaaT"
}
```

### 4. **Summary Message Type** (`type: "summary"`)
```typescript
{
  type: "summary",
  summary: string, // e.g., "Claude Initializes Codebase Documentation Guide"
  leafUuid: string
}
```

### 5. **Content Item Types**

#### **Text Content**
```typescript
{
  type: "text",
  text: string
}
```

#### **Tool Use Content**
```typescript
{
  type: "tool_use",
  id: string, // e.g., "toolu_01TAVcorcBbbKk88KTUwAXeW"
  name: string, // Tool name like "TodoWrite", "Read", "Bash", etc.
  input: Record<string, any> // Tool-specific input parameters
}
```

#### **Tool Result Content**
```typescript
{
  type: "tool_result",
  tool_use_id: string, // e.g., "toolu_01TAVcorcBbbKk88KTUwAXeW"
  content: string,
  is_error?: boolean
}
```

### 6. **ToolUseResult Types**

#### **Simple String Result** (for errors)
```typescript
toolUseResult: string // Error message
```

#### **Command/Bash Result**
```typescript
toolUseResult: {
  stdout: string,
  stderr: string,
  interrupted: boolean,
  isImage: boolean
}
```

#### **File Read Result**
```typescript
toolUseResult: {
  type: "text",
  file: {
    filePath: string,
    content: string,
    numLines: number,
    startLine: number,
    totalLines: number
  }
}
```

#### **Todo Management Result**
```typescript
toolUseResult: {
  oldTodos: TodoItem[],
  newTodos: TodoItem[]
}

// Where TodoItem is:
{
  id: string,
  content: string,
  status: "pending" | "in_progress" | "completed",
  priority: "high" | "medium" | "low"
}
```

#### **Edit Result** (inferred from keys found)
```typescript
toolUseResult: {
  oldString: string,
  newString: string,
  replaceAll: boolean,
  originalFile?: string,
  structuredPatch?: any,
  userModified?: boolean
}
```

### 7. **Special Message Features**

#### **System Messages with Command Structure**
User messages can contain system command information with XML-like tags:
```typescript
{
  type: "user",
  message: {
    role: "user", 
    content: [{
      type: "text",
      text: "<command-message>init is analyzing your codebase…</command-message>\n<command-name>init</command-name>\n<command-args></command-args>\n<command-contents>{...JSON content...}</command-contents>"
    }]
  }
}
```

### 8. **Optional Properties**
- `isMeta?: boolean` - Found in some objects but rare
- `requestId?: string` - Only present in assistant messages
- `toolUseResult?: ToolUseResult` - Only present in user messages that are tool results

### 9. **Data Patterns Observed**

1. **Message Threading**: Messages are linked via `parentUuid` creating conversation chains
2. **Session Management**: All messages in a conversation share the same `sessionId`
3. **Tool Flow**: Tool use follows the pattern: Assistant sends tool_use → User responds with tool_result + toolUseResult
4. **Content Polymorphism**: Message content can be either a simple string (user messages without tools) or an array of content items
5. **Error Handling**: Errors can be represented as simple strings in `toolUseResult` or structured objects with `is_error: true`

This structure supports a rich conversation format with tool integration, file operations, code editing, and system command execution, all tracked with proper threading and session management.
